Your friend surveyed 100 people who took either vitamin C, zinc, or Echinacea supplements to prevent getting a cold. The participants were asked if they had a cold or no cold in the last 30 days. no cold cold total
vitamin C 41 15 56
zinc 12 5 17
echinacea 21 6 27
total 74 26
What ratio of people in the survey took Echinacea?
What ratio of participants who took vitamin C reported having a cold in the last 30 days?
What ratio of people who reported having a cold took zinc?

write out the polynomial, with leading coefficient 1:

y = 1 (x+2)^1 (x-7)^1 (x-5)^2

next time, share the answer choices.   .

measurement of the swimming pool is given as = 7 yards 4.79 feet

first we will convert this to yards only.

1 foot = 0.33 yards

so, 4.79 feet = yards

so total yards are = yards

now we will convert this in meters.

1 yard = 0.914 meters

8.580 yards = meters

0.842 m = 0.842*100 = 84.2 cm

this becomes 7 meters and 84.2 cm

hence, the pool is 7 meters and 84.2 cm wide.
